IMPROVEMENT IN BRAID.

TO ALLWHOM IT MAY CONCERNA:

Beit known that we, J`. HUNT SMITH, of Norwich, in the county of New London, and State of Connecticut, l,

and WILLTAMSHEDLOCK and'ALrRED SnEnLoCK, of the city of New York, and county and State of4 New York, have invent-ed a new and improved Manufacture ot' Braid, whichrjve have named Triradate Braid; and we do hereby declare that. the following is a full and correct description thereof, reference 'being had to theannexed drawings, and to theletters otlreference thereon.

Our invention" consists in a new and improvedbraid, composed of three radial members, united to each other byinterlocking or interbraiding the strands or threads of the three members-of the braid with each other at one edge cf each braid, `so. as to form a triradiate braid, or braid composed of threesrnemgbers, radiating from a common centre, substantially as hereinafter described. ,l i

The drawingsfannexed illustrate three dierentmodes of making the braid, and a frame,- which may be used `in making the braid by-hand. i

. Figure 1 is a planviewof the braiding-frame.

Figures 3,4, ,5,7 6, Y, 8, are plan views and sections of the triradiate braids.

In carrying out our invention, we use 'a frame, a, of the form shown in gs. 1 and 2, which has in the middie of 4it a triradiate slot, composedof three radial slots, b e d, opeuingfinto each other at the commonv centre. The threads forming the strands for each member of the braid 'are introduced into these slots, and secured to a -triradiate. hook, e, to whichv a weight 4or 'tension-cord may be attached., The threads o'f the diierent members of the braid are thus disposed in three,groups,fgft, and each thread of each group has an appropriate notch, to hold it in positionwhen at rest. One of the groups 'has an odd number of threads, .that Visto say, one more thread than each ofthe other two, which have' an even' number of threads.' Starting from this point,.th.e tri- T he mode of braiding the triradiate braidrshown in figs. 3v arg1 4, in which the several threads or strands of cach member of the-braid'run through all the oth`ers, as sh'own by the red line in gs. 3 and 4, isk as follows: lBeginning', with the group of threads,f, the first thread z' is taken and passed over the next thread, j, and

i securedin'the notch'occupied'by thread j, thelatter being removed into thenotch occupied by the first thread z', and this being done toeaeh oivithc pair ofthrea'ds succeeding, until the last thread of the group is reached, which is anodd thread, when this 'process of interlocking the' threads by pairs is reversed, beginning with the odd thread, and carried on, pair by pair, until the round is conipleted, lwhen the viirst threadz' will have gone to the notch k, and artodd thread iv'ill occupy the notch z'. This latter odd thread, which now occupies the notch t', is then transferred to the group g, and placed in thenotchm of that group, which will then have the same number of threads, disposed in the same manneras they were in the grou-p fr' The braiding ,by pairs of threads'. then lgoes on in the group g, in the saine manner as before iu group f,"unti'l the"round is completed,V when the odd strand is transferred vto the notch 1 1, of group It, `and a round havingheenbraided `in the same manner in the group h, vthe last or odd thread is transferred to the rstv group, and so von, until a sulicient length of braid is braided. Y

In braiding a triradiate braid in this manner, all the threads of each member ofthe braid pass into `and through the web ofY each ofthe other members, as shown b'y the red lines. I The mode of braiding the triradiateA braid,l shown in figs. 4 and 5, in which the threads of each4 member ofthe braid merely interlock atthe edges, and `thereby a braid-can be made in which thethree members are of adierent color from each other, is :1s-follows: f l

Let`the three groupsof threads be composed of lthe same number ofthreads, say eight, or'any eilen number, and, after braiding a rcund,as before described, on the first group, take the last thread of the round, which is the first thread of the group, from its notch, and interlock't withtheiirst thread of the next group, restoring both threads to their respective notches, in their respective group, then braid a round on the second group, and take the last-thread of the round and interlock it with the .rst thread ofthe third group, and so on, keeping the threads of each group-by themselves, and forming the triradiate braid by simply interlocking the members of the braid at their edges. y l i The mode of braiding the-triradiate braid, shoivn in gs. 7 and.8, in -which the threads of two of the members interbr'aid or r-un into each other, but only interlock with the third-member, is as follows: I

Let the two groups of threads which arc to run intov or interbraid with each other, be composed of an unequal number of threads, that is to say, one of the two groups have one more thread than the other, as in the groups f and g, iig'. 1, and let these'groupsbe disposed relatively to eac-l1 other and t'othc third group, as are the lgroups f, g, and la, in g. 1. 'The third .group may be composed of any number of threads desired, or, as shown in tigs.-7 and 8, of smallernumber of threads than thepther groups.

The braiding begins with the group'f by braiding a round, as before described, and transferring the last thread in the round to thenotch m in the group g, but, in making this transfer, this thread must be interlocked with the rst thread in the third group. A round is then braided in the third group, answering to group h, in fig. 1, followed 'by a round in the s econd group, the last thread of the round being transferred to the notch z', in the first group f, the s-eries of operations being repeated until a braid of suflcient length is braided.

In the mode of braiding last described, the threads of the groups fand gniay be arranged iu one group, in a straight or curved line, as if to make a dat braid, with the threads of the other group in a line, intersecting the middle of therst, but, in that case, the mode of braiding would be the same in substance as the last, because the middle thread of the double or wide group would always interlock at every round with the first thread of the second group.

One of the advantages of our new and improved manufacture of triradiate braid is, that the braid can be more readily applied to the edges of garments, especially when sewingmachines are used, the use of ordi#- nary braid being difficult in binding with a sewing-machine. It has also the advantage of making atlatter and rmer edge when bound on an edge of a garment.

The members of the triradiate braid may be of the same width, or of different widths, and one member may be made thicker than the other two, by using heavier threads and braiding closer. y

We have shown ldiierent modes of making our triradiate braid, but do not wish to limit ourselves to any special mode of manufacture, or to any-kind of materiahlor color-,or combination of colors.

We claim as our invention, the new and improved manufacture herein described of a triradiate braid, or braid composed of three radial members, united to each other by interlocking or interbraiding the threads of the different members with each other, substantially as herein described.l
